Periodontally accelerated osteogenic orthodontics (PAOO) is a clinical procedure that incorporates selective corticotomy, particulate grafting, and application of optimal orthodontic forces. It reduces treatment time, increases stability of teeth, and prevents relapse of orthodontic tooth movement (OTM). The present case report highlights the technique and principles of PAOO for rapid OTM.

Limb lengthening by Ilizarov lengthens not just the long bone, but also the soft tissues too. Damage of the muscles during corticotomy and their stretching during distraction play a crucial role in occurrence of complications and final limb function. We present here a systematic codified nomenclature system of each muscle summarising all the influence that corticotomy and distraction have the particular muscle and demonstrate the same in the setting of tibial lengthening. This scheme helps the surgeon easily recollect what all muscles are involved in what all ways in each level of corticotomy thus enabling him to watch out for complications thereof and monitor and accordingly modify the limb lengthening process...

True intrusion is one of the difficult and complex goals to achieve which requires clinical judgment, skills, and experience. Intrusion requires less force level than other tooth movement, but it requires delicacy since the entire stress is concentrated in the apex of the root. Although true intrusion alone is not challenging, eliminating the adverse effect while intruding requires tedious skills of the clinician. A 17-year-old male patient with Class I malocclusion with open bite has a prominent maxillary cortical bone...

The number of adults seeking orthodontic treatment is increasing. Shortening the course of orthodontic treatment has become a research hotspot in recent years. Methods of accelerating tooth movement have been reported. Theoretical and clinical studies have confirmed that periodontal corticotomy is effective in accelerating tooth movement and increasing osteogenic potential. Many surgical techniques of periodontal corticotomy have been developed. This review summarizes the history of periodontal corticotomy and the development of the surgical techniques in recent years, thereby providing references for the clinical application of corticotomy...

Conventional surgical treatment for cerebral abscesses includes craniotomy or stereotactic aspiration. Deep-seated, large abscesses pose a challenge to neurosurgeons, due to the risk of injury to the cortex and white matter tracts secondary to the brain retraction necessary to access the lesion. The endoport is a tubular conduit that can be employed for minimally invasive approaches to deep-seated intracranial lesions, and it may reduce the length of dural opening, size of corticotomy, and retraction-related injury...
